Technical content
/ BIPOLAR ANALOG INTEGRATED CIRCUIT VERTICAL DEFLECTION CIRCUIT OF COLOR TV The uPC1498H is a vertical deflection output IC for large size color TV application more than 22 inches tube. As a boost pulse is generated internally, this IC is systematically connected with uPC1401CA or uPC1B00CA. The package of 8 pin power SIP, attached to heat-sink by one screw, decreases work-loading for assembling.
